Title: In-circuit testing apparatus
Inventor: YOKOGAWA HIROMICHI
IPC: G01R31/02
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain an in-circuit testing apparatus that can detect the existence of a short circuit across terminals, by detecting the radiant waves of a supplied signal near the terminal of an electronic component and judging the connection state of the terminal of the electronic component on the basis of the radiant waves. SOLUTION: The tip of a probe 22 for signal application is brought into contact with a node pad 51 on a printed-circuit board, and the tip of a probe 31 for signal detection is installed at the upper part near the lead terminal 41 of an IC package 40. Then, the pulse waves of a signal source 21 are applied to the probe 22 for signal application. When the lead terminal 41 is soldered to the node pad 51, the pulse waves applied to the node pad 51 are transmitted to the lead terminal 41, the radiant waves of the pulse waves appear at the upper part near it so as to be detected by the probe 31 for signal detection. The radiant waves are amplified by a signal amplification part 32, and they are converted into a digital signal by an A/D conversion part 33 so as to transmitted to a judgment part 34.  The judgment part 34 stores the digital signal as measured data, it compares the signal with a preset signal level, and it judges the connection state of the lead terminal 41, i.e., whether a soldering operation is proper or not.

Title: Interface circuit
Inventor: NAGAI HIDEO
IPC: H03K19/0175
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To surely prevent destruction of an output circuit provided with an output buffer even in the case that no power is supplied to an input circuit provided with an input buffer. SOLUTION: When the power supply level of a power source 5 is lowered to a voltage by which a CMOS circuit 6 is not normally operated, since the voltage of an output control circuit 8 is also lowered, the output of the output buffer 9 of the output control circuit 8 is turned to a high impedance state. At the time, since a signal line 101 is pulled up by a pull-up resistor 4, the output of the output buffer 9 becomes 'H' and the output tri-state buffer 3 of the CMOS circuit 2 is turned to the high impedance state. As a result, since the signal line 100 is also turned to the high impedance state, the inflow of a current from the CMOS circuit 2 to the CMOS circuit 6 does not occur and the output tri-state buffer 3 of the CMOS circuit 2 is prevented from being destroyed.
